D3612 (version 02(2017))

1.1 This test method covers three procedures for extraction and measurement of gases dissolved in electrical insulating oil having a viscosity of 20 cSt (100 SUS) or less at 40°C (104°F), and the identification and determination of the individual component gases extracted. Other methods have been used to perform this analysis.

1.2 The individual component gases that may be identified and determined include:

 

Hydrogen—H₂

 

Oxygen—O₂

 

Nitrogen—N₂

 

Carbon monoxide—CO

 

Carbon dioxide—CO₂

 

Methane—CH₄

 

Ethane—C₂H₆

 

Ethylene—C₂H₄

 

Acetylene—C₂H₂

 

Propane—C₃H₈

 

Propylene—C₃H₆
